>The app reportedly scans for the MD5 digital signatures of media files in the phone, and matches them to a stored database of offending files classified by the government as illegal "terrorist-related" media.

What a dumb way to scan for "illegal" content, considering the goverment already controls their portion of the internet. So instead of monitoring who is accessing what they decide to compare checksums of files which can be trivially changed which would result in a completely new hash value.

Seems like a very incompetent way of doing this.

This is interesting. It goes to show how an autoritarian government can fix some problems in a more effective way. You can remove terrorist propaganda from YouTube, but how do you stop the spread of those videos in private platforms or messaging applications?

And even if the first version of this spying app only checks for md5 sums, which is arguably useless, I'm sure they're working on something more effective.

I can think of so many countermeasures.

- Append a null byte to the end of your files, giving them a unique hash value.

- Disallow internet access to the application.

- Spoof the server using DNS tricks and control what is sent and received.

- Reverse engineer the application to make it look as if it's working while it actually isn't.

- Sandbox the application.

- Use an alternative phone for all of your "sensitive" activities.

- Don't keep "sensitive" information on phones, rather store on an encrypted computer.

- Use an old burner phone.

So not only is the policy utterly disgusting, it's also completely ineffective. A small blessing perhaps.

Wow, those chinese surely are totalitarian in the way they approach surveillance technology aren't they ?

Good thing we have nothing like that. Only just closed hardware with closed or with some parts open complicated software mostly made by a few corporations which tend to and have in fact in past coopoerated with governments without even thinking about their customers.
